Get database connection information (host, port, credentials)
AI agents call liara_get_database_connection to retrieve information from Liara MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves existing connection details without creating, modifying, or deleting any infrastructure. However, exposed credentials (passwords/tokens) represent a moderate risk if returned to an AI agent, which could inadvertently log or mishandle them. This is classified as Read with medium severity due to the sensitivity of the returned data, not due to any destructive capability.
From the tool's definition Tool retrieves connection information (host, port, credentials) with no side effects. Description explicitly uses 'Get', a read operation. Database credentials are sensitive, elevating severity despite no data modification capability.
Documented attack patterns abuse exactly the kind of access liara_get_database_connection gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Liara MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for liara_get_database_connection:
{
"version": "1",
"default": "deny",
"tools": {
"liara_get_database_connection": {}
}
} liara_get_database_connection is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get database connection information (host, port, credentials). It is categorised as a Read tool in the Liara MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Liara MCP Server MCP server in PolicyLayer and add a rule for liara_get_database_connection: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Liara MCP Server. Nothing to install.
liara_get_database_connection is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the liara_get_database_connection rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for liara_get_database_connection. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
liara_get_database_connection is provided by the Liara MCP Server MCP server (razavioo/liara-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Liara MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
